It depends on the fraction. For the following, assume the denominator is not zero, for if it is, then the fraction is undefined.
- If the numerator and denominator are both rational, then the fraction is rational.
- If one of them is rational and the other is irrational then (provided the numerator is not 0), the fraction is irrational.
- If both are irrational you need to simplify first and then apply one of the above two criteria.
For example, sqrt(2)/sqrt(8) = sqrt(2/8) = sqrt(1/4) = ±1/2. So, irrational/irrational
can be rational.
